Crazy random (mostly Loke) doodles

This is the sort of practice sheet I make, just doodles, most of them copied or inspired from manga and random online pictures, which then get clustered on a single sheet of paper (don't want to waste paper) until I decide to scan them in to be manipulated, redrawn, lined, and colored on the computer. I should mention, this page also has a huge picture on the back side that was going to be my Halloween entry, but it'd be super complex if I draw it at the detail I'd like, so that "doctor and nurse" pic will do and is the first pic to get my work. I'm fairly certain that was from Maid-sama, but slightly redrawn to be Lucy and Loke. I know the short-haired Loke in a bath towel was Maid-sama. The top right corner is a potential picture for a fanfic bookcover, with Natsu, Gray, and Loke (ignore retard-hair Gray). The central face was going to be something bigger but I gave up before I even got to the hair, yet the eyes turned out perfect. No clue where that bottom left corner pic came from, but it has potential!
